Syntax

Finding out the size of a file according to its path Hide the details

<Result> = fSize(<File path>)

<Result>: Integer

Size of the file (in bytes),
-1 if an error occurred. To find out the error details, use ErrorInfo associated with the errMessage constant.
When handling files exceeding 2 GB, <Result> must correspond to an 8-byte integer.

<File path>: Character string (with quotes)

Name and full (or relative) path of file (up to 260 characters). A UNC path can be used. The wildcard characters (* and?) are not allowed.
Versions 15 and later

This parameter can correspond to a full path or to a relative path in relation to the current directory (returned by fCurrentDir). This parameter is case sensitive.
Reminder: In Android, the file system is read-only on the device and on the emulator. An application has the rights to write into its setup directory or into one of its subdirectories, as well as onto the external memory (SDCard).
